Take control of your wireless audio with the CX 350BT Wireless In-Ear Headphones from Sennheiser. These headphones work with Bluetooth-compatible devices, but are ideal for smartphones, with support for digital assistants and built-in mics for hands-free calling. An inline remote and Smart Control App give you control over music playback, incoming calls, voice commands, and sound quality. With support for the aptX Low Latency codec, that sound quality is engineered to be consistent, high quality, and in sync with gaming and streaming media.

Smart Control App

Available for iOS (11.0 and up) and Android (7.0 and up) devices, this app provides an equalizer that allows you to customize audio playback to your liking. There's also a podcast mode, the ability to download firmware updates to upgrade performance, and more. The app is available in 8 different languages: English, German, French, Spanish, Russian, Korean, Japanese, and Mandarin.

Calls & Commands

An integrated microphone gives you the ability to take hands-free calls and give voice commands to your mobile device's digital assistant software. All while leaving your smartphone or tablet safely tucked away in a bag or pocket.

Wired Convenience

Not every cable is cut with the CX 350BT headphones. Each earbud is connected together with a lightweight cable that features an inline remote and battery. This wired design makes it easy to drape around your neck when you're not listening, while still being ready to go when you want to get back to the music.

Long Battery Life

The integrated battery of the CX 350BT headphones gives you up to 10 hours of wireless playback.

Use with Two Devices

Supporting multipoint technology, the CX 350BT wireless headphones can pair with two compatible devices simultaneously. So if you're gaming or streaming a movie on your tablet, you can quickly answer a call on your smartphone.

Comfortable Fit

Four pairs of different sized eartips are included. You get a pair in extra small, small, medium, and large. This allows you to better customize the fit and comfort of the CX 350BT headphones, and increase their passive noise isolation.
